> There are two bugs in these two methods: First, the number of digits on the right of the decimal point is wrongly calculated:
> 1.2345 -> String of length 6, decimal point on index 1
> the number of digits on the right of the decimal point is length - decimalPointIndex -1. The -1 was missing.
> The second bug is the following. If a  String containing "1.00" is  converted to a Double or Float (using Double.parseDouble() or Float.parseFloat()) and then converted back (using Double.toString() or Float.toString()) it will result in "1.0". if minDecimal was set to 2 (and the first bug was fixed) the methods will actually return false.
> I added some Unit-Tests to BaseUnitTests.java to express this in code.
